<pre>Allow builtin JS functions to be intrinsics
https://bugs.webkit.org/show_bug.cgi?id=155960
Reviewed by Mark Lam.
Source/JavaScriptCore:
Builtin functions can now be recognized as intrinsics inside
the DFG. This gives us the flexibility to either lower a builtin
as an intrinsic in the DFG or as a normal function call.
Because we may decide to not lower it as an intrinsic, the DFG
inliner could still inline the function call.
You can annotate a builtin function like so to make
it be recognized as an intrinsic.
```
[intrinsic=FooIntrinsic] function foo() { ... }
```
where FooIntrinsic is an enum value of the Intrinsic enum.
So in the future if we write RegExp.prototype.test as a builtin, we would do:
``` RegExpPrototype.js
[intrinsic=RegExpTestIntrinsic] function test() { ... }
```
